FINGER-RING TWINE-CUTTER.

SPECIFICATION forming part of Letters Patent No. 611,313, dated September 27, 1898.

Application filed November 22, 1897. Serial No. 659,383. (No model.)

To all whmn it may concern:

Be it known that I, JACOB ORANDALL, a citizen of the United States, residing at Westport, county of Mendocino, State of Oalifornia,have invented an Improvement in Finger Ring Twine-Cutters; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a twine-cutting attachment for finger-rings; and it consists, essentially, in a peculiar construction of the 7 ring with bracing-arms and a means for re- *movably seating the cutting-blade therein and exposing the edges and guides by which the twine is brought into contact therewith.

Referring to the accompanying drawing, the figure is a view of the ring.

In the application of cutters of any description to a ring or device by which it may be conveniently held upon the finger of the operator it has been difficult to prevent the ring from turning when pressure is brought upon it 3 and my invention is designed, primarily, to hold the ring in its proper position, preventing its turning, and providing a proper resistance when the twine is being out.

A is a ring of suitable size to fit the finger of the user, and this ring has a head 13 proj ecting outwardly from it. This head is made integral with the body of the ring and has lugs or arms I) Z) projecting from the upper part, following the line of peripheral curvature of the ring, and at such a distance therefrom as to leave open channels between these ends I) and the body of the ring. This head is made of approximately the same thickness as the ring and it has a V-shaped slot made through it, the length being sufficient to receive a knife or cutter G. This knife or cutter is of tapering or wedge-shaped form, being the widest at the top, tapering downward, so that it will fit snugly into the slot or channel and so that its sharpened edges are presented across the openings formed between the body of the ring and the projections 19, so that a thread or twine drawn into either of the openings will be brought into contact with the edge of the cutter, and thus severed. This cutter is seated in a correspondingly-shaped channel, as before described, and is secured in place by a small screw 0, passing transversely through it and removable at any time for the purpose of removing and sharpening the cutters.

In order to prevent the ring being turned by the pressure brought upon one side of it when the twine is introduced to be cut, I have shown projecting curved arms D extending in either direction from the body of the ring,with which they are made integral, and upon the opposite side to the cutter. These arms are curved to fit within the fingers adjacent to the one upon which the ring is worn,.while the cutter itself is on the exterior or outside the fingers. The curvature of the arms is approximately the same as that of the ring itself, and these arms act as braces, pressing against the adjacent fingers to prevent the ring being turned when the twine is being cut.

The contrivance is exceedingly effective and convenient for the purpose required.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A thread or twine cutter consisting of a ring having a head projecting upon one side with arms projecting therefrom in the line of curvature of the ring, forming channels between themselves and the ring upon each side,

a tapering or V-shaped knife having cutting edges upon each side adapted to fit a correspondingly-shaped channel made inthe head of the ring whereby the cutting edges cross the openings upon each side of the head, a removable screw by which the cutter is held in place and means for preventing the ring from turning upon the finger consisting of the curved lugs formed integral with the ring and projecting upon each side substantially as described.

2. A ring fitted to the finger of the user having an exterior cutting-knife, and curved arms extending upon each side of the opposite portion of the ring and adapted to engage the inner part of the fingersadjacent to the one upon which the ring is worn.

In witness whereof I have hereunto set my hand.
